Abstract :
A 3 dB gain bandwidth of 75 nm (1531-1606 nm) is realised in a novel configuration of a two-stage erbium-doped fluoride fibre amplifier with a discrete fibre Raman amplifier. Error-free operation in an in-line amplifier configuration is also confirmed through a WDM (2.5 Gbit/s×9 channel) transmission experiment
